NAME

       vrb_write - write data from a VRB

LIBRARY

       -lvrb

SYNOPSIS

       #include <vrb.h>

       size_t vrb_write(vrb_p vrb, int fd, size_t size);

DESCRIPTION

       vrb_write  writes  data  to  a  specified  open  file  descriptor  using write(2) from the
       specified virtual ring buffer until the specified maximum length  has  been  written,  the
       buffer  is  full,  or  an  error  is  returned (including EAGAIN or EWOULDBLOCK for a non-
       blocking descriptor).

ARGUMENTS

       vrb_p vrb
       specifies which virtual ring buffer.

       int fd
       specifies the open file descriptor to write to

       size_t size
       specifies the maximum length to write, or ~0 for unlimited (all of buffer).

RETURN VALUE

       size_t
       If successful, the actual length of data written from the buffer is returned.  If no  data
       was  available  to  be written, 0 will be returned.  If an error occurs from write(2), the
       return value is ~0 and errno is set by write(2).

ERRORS

       If an error is returned, then errno will have one of the following values:

       0      An end-of-file has occurred.  Note that this is a different  way  of  returning  an
              end-of-file condition than write(2) uses.

       EINVAL An invalid virtual ring buffer pointer was specified.
